+Deepcopy support
+================
+
+Python normally uses references in assignments. Sometimes a real copy is needed
+to prevent changing all copies. The ``copy`` module [#f5]_ provides these
+capabilities.
+
+On Python 3, a class with pickle support is automatically also (deep)copy
+compatible. However, performance can be improved by adding custom
+``__copy__`` and ``__deepcopy__`` methods. With Python 2.7, these custom methods
+are mandatory for (deep)copy compatibility, because pybind11 only supports
+cPickle.
+
+For simple classes (deep)copy can be enabled by using the copy constructor,
+which should look as follows:
+
+.. code-block:: cpp
+
+    py::class_<Copyable>(m, "Copyable")
+        .def("__copy__",  [](const Copyable &self) {
+            return Copyable(self);
+        })
+        .def("__deepcopy__", [](const Copyable &self, py::dict) {
+            return Copyable(self);
+        }, "memo"_a);
+
+.. note::
+
+    Dynamic attributes will not be copied in this example.
